Answer:
x = - 8
3x - 2y = 18 is the same as 3x - (2x - 13 times 2) = 18
Then I used an algebra site for the rest.
It should be x = - 8
A study of 600 college students taking statistics 101 revealed that 54 students received the grade of
a. Typically 10% of the class gets an A
b. The difference between this group of students and the expected value is not significant at the 0.05 level. what does this mean in this case?
Your answer would mean that, =====> The probability of getting an A is 10% and only 9% got an A, in this study. The difference is less than 5% therefore, in this case, it is not significant.
Hope that helps!!!! : )
Answer:
y = -3x +10 Step-by-step explanation:
y+2 = -3(x-4)
y+2 = (-3*x) + (-3*-4)
y+2 = -3x + 12
^ -2 = . ^ -2
y = -3x +10
Change the mixed fractions to an improper fraction.
4 5/7 = 32/7
1 6/7 = 13/7
Now you can easily subtract since both fractions have common denominators
32/7 - 13/7
(Think: 32 - 13 = 19)
Change the improper fraction to a mixed fraction
19/7 = 2 5/7
Answer: 2 5/7
Hope I helped =)
